RAILWAY-CAR SILL.

Specification of Letters Patent.

Application filed OctoberBO. 1905. Serial No. 285,157.

To all whom it may concern:

Be it known that'we, THOMAS DUNBAR and ETHAN I. DODDS, citizens of the United States, residing at Pullman, in the county of 5 Cook and State of Illinois, have invented certain new and useful Improvements in Rail Way-Car Sills, of which the following is a specification.

The purpose of our invention is the provision of a metallic side or center sill'for railway-cars which shall combine light weight, strength, and ease of repair, To carry out. this object and'embody'the invention in prac tical form for each sill, we use two end meni- I bers deeper at their inner than at their {outer ends and join these inner ends at their upper parts by any standard form of bar and at their lower parts by atension-rod comprising two pieces united by a turnbuckle. In this 20 attains the object specified.- In the accompanying drawings is illustrated the preferred mechanical embodiment of our invention. I

Figure 1 is a side elevation of one half of the sill, and Fig. 2 is a vertical cross-section on line 2 2 of Fig. 1.

The sill comprises two end beams 10, of which only one is shown in the drawings. Each of these has a top integral inwardly turned flange '11 and a similar bottom flange 12, the inner end portion of each beam being deeper than its outer end portion 10", as shown. A channel-bar 13 with inwardlyextended flanges 14 and 15 overlaps the inner ends of beams 10 at their upper parts, with the flange 14 disposed inside of and adjacent to flanges 11 of the end beams. Rivets 16 secure the parts together, and if it is desired to have the upper surface of bar 13 in the same plane with the upper surfaces of beams 10' the former may be depressed slightly at its ends, as at 17.

At the, lowerportion of the inner end of 18, a pair of spaced cars 19, to which are pivoted at 20 the two portions 21 and 22 of the ,outer surface and the other on its inner Sur-- manner a bellied sill is manufactured which.

each beam 10 is attached, by means of rivetsaving threaded engagement there tension-rod, are connected by a turnbuckle- 23, the rotation of which adjusts the length of the rod. Since the beam is made up of a number of small parts, if one or more become damaged they can be easily repaired or replaced, because they do not involve the han dling or heating of any large parts.

Minor mechanical changes may be made in this Structure without depar-tin from the substance of our invention as defined in the following claims.

\Ve claim- 1. In a device of the character described, the combination of two end beams, a center bar and a rod fastened to and. connecting said end beams, substantially as described.
